Semantics of "virsh migrate --copy-storage-all" vs. --copy-storage-inc
Hello,
what is really the difference between
virsh migrate --copy-storage-all
and
virsh migrate --copy-storage-inc
?
There are some documents talking about NBD snapshots, but the user
visible semantics are incomplete.
Where does the incremental stuff happen?
Does it require qcow2 files?
Does it work with raw files?
Does "--copy-storage-inc" require existing snapshots?

virsh migrate --copy-storage-inc
Hello,
I use libvirt on machines without shared storage. My VM's have all one
qcow2-disk, with the same name as the VM.
When I want to migrate a VM, I check if there is an qcow2 image on the
other host with that name. When that's not the case, I copy the image
using rsync first. If the image excist, I don't do that, and I think
that "--copy-storage-inc" will do it.
But I

non failover equivalent to "virsh migrate --copy-storage-all"
Hello,
I have two servers where I can push VMs from one to the other by issuing
the command
virsh migrate --live --persistent --copy-storage-all --verbose \
test6 qemu+ssh://kvmhost2/system
on kvmhost1. I can get the VM back by issuing the equivalent command on
kvmhost2:
virsh migrate --live --persistent --copy-storage-all --verbose \

post_processor in rmarkdown not working
Dear all,
I'm trying to write a post_processor() for a custom rmarkdown format. The
goal of the post_processor() is to modify the latex file before it is
compiled. For some reason the post_processor() is not run. The
post_processor() does work when I run it manually on the tex file.
Any suggestions on what I'm doing wrong? Below is the relevant snippet of
the code. The full code is

virsh attach makes qcow2 format disk to raw format
Hi all
I have a problem when I use `virsh attach` to attach a qcow2 disk to vm without argument --subdirver=qcow2
and this makes the qcow2 disk become a raw format disk, and the data in this disk is missing in guest os
and also I have used guestmout to confirm this, the same result.
Is there any way to let me find back the data in this disk ?
the version of libvirt and kvm is :

Why are virsh vol-upload/vol-download so slow?
I was interested in using 'virsh vol-upload' and 'virsh vol-download',
rather than mucking about directly with the filesystem. But while
simply copying the image is relatively quick:
# ls -l /var/lib/libvirt/images/centos-7-cloud.qcow2
-rw-r--r--. 1 qemu qemu 1004994560 Apr 15 2015 centos-7-cloud.qcow2

post_processor in rmarkdown not working
Dear Duncan,
Thanks for chiming in. Could you explain how you set debug() on
post_processor()? I've tried adding debug(post_processor) to rsos_article()
or adding debug(post_processor) when after post_processor was defined in
the debugger. Neither work for me.
All supporting files are available within the package. The code below
should be reproducible on your machine.

Hi,
I noticed the diff wasn't showing the "-" at the start of a deleted file
and the details of the second file when attributes are different.
This change should fix them.
thanks.
